Stellaris® Serial-to-Ethernet Reference Design Kit » RDK-S2E

The Stellaris® Serial-to-Ethernet Reference Design Kit(RDK-S2E) offers a complete, open-tool, and ready-to-implement solution designed to add web connectivity to any serial device. Included in the RDK-S2E is the tiny-footprint Stellaris® Serial-to-Ethernet Module (MDL-S2E).The most common application for the MDL-S2E is for augmenting legacy products that only contain a serial port for a configuration or control interface. In addition, newer computers, especially laptop computers, do not necessarily have serial ports, and a serial connection is limited by cable length (typically 10m). Simply installing a Stellaris® Serial-to-Ethernet Module into the legacy serial device provides many benefits including no major board redesign or software changes, easy sharing on a network other than Ethernet, tinyform-factor for unobtrusive implementation, and 10-meter maximum cable length for serial connections is no longer a limitation.

The MDL-S2E is the first serial-to-Ethernet converter available with a highly integrated ARM® Cortex™-M3 microcontroller with 50 MHz of performance and ample single-cycle, on-chip Flash and SRAM memory for efficient network traffic handling. For maximum space savings, the Stellaris® microcontroller is offered in a small BGA package and integrates the 10/100 Ethernet MAC and PHYon-chip.

Features

10/100 Mbit Ethernet port

Auto MDI/MDIX cross-over correction

Traffic and link indicators Serial ports

UART ports include RTS/CTS for flow control

UART0 has RS232 levels, transceiver runs at up to 230.4 Kbaud

UART1 has CMOS/TTL levels, can run at 1.0 Mbaud

Software

IP configuration with static IP address or DHCP

Telnet server for access to serial port (VCP software included)

Web server for module configuration

UDP responder for device discovery

Telnet client for Ethernet-based serial port extender

Module supports 5 V and 3.3 V supplies

Multiple mounting options

JTAG port pads for factory programming
